Pressure and Gas Flow Gradients Behind the Projectile During the Interior Ballistic Cycle
Abstract
A very important factor in determining the projectile acceleration in a lumped parameter ballistic model is the relationship between the computed parameter, the space mean pressure, and the parameter defining the projectile motion, the pressure acting on the base of the projectile. The gradients of pressure and density from the breech to projectile were postulated to depend on the term, projectile acceleration times axial position. The model compared favorably with experimental measurements of downbore to chamber pressure ratios. Keywords: Interior ballistics, Gas gradients.
